As in previous years, Eric Siebert with vSphere-land.com is organizing a TOP vBlog voting competition and my blog, ESX Virtualization blog, is participating. I try to do a bit of everything, but staying as accurate as possible. Readers can vote and determine which virtualization blog they prefer to read through the year. Some readers might prefer deep-dive, or how-to topics only where others want to read news or watch videos.
I’ve been working on some different things lately and wanted to share with you a tool I used to help verify data. Whilst I am not ready to reveal all that I am working on I have had the requirement to return the following information about a Virtual Machine – Name, IP Address, MAC Address, Attached Network, Power State, VMtools status, and the VMtools version.
There’s no question about it: Network Virtualization is the future. As virtualization moves in to replace the hardware-centric networks of yesterday and today, the most sought after IT practitioners will be those who know Network Virtualization inside and out. Staying competitive in IT means growing your knowledge, building marketable skills, and developing virtual savvy
In Part 1 of this blog, I discussed how you can monitor vCenter’s vPostgres database remotely using Blue Medora’s Management Pack for PostgreSQL. For those of you with larger environments with Oracle or MS SQL databases supporting vCenter, you’ll want to monitor those as well. In this blog I’ll step through how one can monitor a Microsoft SQL server remotely using vRealize Operations Manager. Similar steps can be taken to monitor an Oracle database remotely with Blue Medora’s Management Pack for Oracle. This includes setting up the requisite credentials on the SQL server, creating relationships to vCenter, and a custom dashboard that shows SQL performance for vCenter.
Over the last year the number of Virtual Volumes implementations has increased significantly. From a handful of key VVol partners in early 2015 we now have over 150 array models certified for VVols from 15+ partners with more on the way. Given this rapid growth in support for VVols we have heard from customers that the VMware Compatibility Guide for Virtual Volumes needs to be updated to make it faster and easier to use.
The recent rash of cyber security breaches at well-known retail companies and government websites have made it excruciatingly clear that businesses today need a better solution to network and data security. Research shows that more than 30 percent of data center outages are caused by cyber attacks, and a 60-minute outage can cost businesses upwards …
Out of many reasons, I need VMware ESXi version information in a format that can be reused in scripts. I maintain a manual list since a couple of years but this list can’t be used for automation purposes. VMware does not provide this information in the required format, so I created my own database which is now also available as JSON file.
After upgrading the VCSA to the latest U2 and also with new machine certificate , noticed vSphere Replication was in failed status and when I tried to configure the lookup service address and restarting the service it was failing with the error BAD EXIT CODE:1.
Today while working in my lab I was facing one issue when I was trying to install vCenter Server on top of Server 2012. I was experimenting to deploy vCenter Server with external SQL 2014 database. This was my first experience with working on external database for vCenter Server and I knew I am gonna face some issues.
We all know that SSL certificates enable secure communication between a browser and a web server. During the initial setup, all the VMware components are installed with self-signed certificates and it is a best practice to replace the default certificates with custom CA signed certificates. This process of replacing default certificates in vSphere 6 is very simple compared to the tedious process that was present in the previous versions of vSphere (5.1 and 5.5).
When installing Photon Controller, the resource configuration of the Management VM is sized dynamically as mentioned here based on the total available CPU, Memory and Storage on the physical ESXi host that it is being provisioned to. This is generally not a problem when deploying Photon Controller in Production with larger hosts but if you are trying to play with it in a home lab or a resource constrained environment, then this can be a challenge.
I was so excited to see that the Hands-On-Labs (HOL) had finally been updated to Virtual SAN 6.2 that it prompted this blog. I just couldn’t stop at HOL! The VMware storage & availability team offers many other nifty tools to get you started with VMware Virtual SAN. If you haven’t yet, check out these 6 tools to get you on the path to hyper-convergence.
I was recently talking one of the customers where the Virtual Machine was showing up on one of the wrong Storage clusters. On further investigation, I found that this was happening due to the fact that the ISO mounted on the Virtual Machine was coming from one of the datastores that were part of another datastore cluster.
